hey its coming along.. normally i would suggest to post renders other than normal mats (i.e. clay, wire... etc). but ithink its safe to say that your a beginner and prob dont know how to. if u can post a clay so we can c bumps.
Try and get a a few mor details in for instance look at this picture

and you will see that the headlights are actually inside the front not on the outside. also add the body lines that are on the side of the car. Even if you think you dont have enough skill to do it, still do it because u can only learn from mistakes... and people can point out any errors you might have and how to go about fixing them.. i always say its better to be over your head than under it
... but try and get as much detail as possible
also fix the weld line down the symmetry line of the car. do this by aligning those vertices from the side viewport and make it exactly the same point on the x axis and the symetry on the x axis... also make sure that the symmetry modifier is below the meshsmooth (or turbosmooth) modifier on the modifier stack...
Good Luck
